These people call me at least once a day. They call when I'm sleeping or at work. I've learned to simply ignore them at work, but when they wake me up, I think it's the job calling and run to the phone.
I received a call on my mobile phone from this number at about 4PM EST on Tuesday 14Aug07. No message was left, of course. The caller showed "Nebraska" as the source of the call while it was ringing.
